How is true possession to be distinguished from fraud or the symptoms of disease? The Church prescribes four tests—the language test, the test of preternatural physical strength, the test of levitation and the test of clairvoyance and prevision. If a person can on occasion understand, or better still, speak a language, of which, in his normal state, he is completely ignorant; if he can manifest the physical miracle of levitation or perform unaccountable feats of strength, and if he can correctly predict the future or describe events taking place at a distance—then that person may be presumed to be possessed by devils. (Alternatively, he may be presumed to be the recipient of extraordinary graces; for in many instances divine and infernal miracles are, most unhappily, identical. The levitation of saintly ecstatics is distinguishable from the levitation of ecstatic demoniacs only in virtue of the moral antecedents and consequences of the event. These moral antecedents and consequences are often hard to assess, and it has sometimes happened that even the holiest persons have been suspected of producing their ESP phenomena and their PK effects by diabolic means.)
Such are the official and time-hallowed criteria of diabolic possession. For us, these ESP and PK phenomena prove only that the old notion of a completely watertight soul is untenable. Below and beyond the conscious self lie vast ranges of subconscious activity, some worse than the ego and some better. Some stupider and some, in certain respects, far more intelligent. At its fringes this subconscious self overlaps and merges with not-self, with the psychic medium in which all selves bathe and through which they can directly communicate with one another and with cosmic Mind. And somewhere on these subconscious levels individual minds make contact with energy, and make contact with it not merely in their own body, but also (if the anecdotic and statistical evidence may be trusted) outside their own body. The older psychology, as we have seen, was compelled by its own dogmatic definitions to ignore subconscious mental activity; in order to account for the observed facts, it had to postulate the devil.
For the moment, let us place ourselves in the intellectual position of the exorcists and their contemporaries. Accepting as valid the Church’s criteria of possession, let us examine the evidence on which the nuns were pronounced to be demoniacs and the parson, a sorcerer. We will begin with the test which, because it was the easiest of application, was in practice the most frequently applied—the test of language.
For all the Christians of an earlier day, “speaking with tongues” was an extraordinary grace, a gratuitous gift of the Holy Spirit. But it was also (such is the strangely equivocal nature of the universe) a sure symptom of possession by devils. In the great majority of cases, glossolalia is not a clear and unmistakable speaking of some hitherto unknown tongue. It is a more or less articulate, more or less systematic gibberish, exhibiting certain resemblances to some form of traditional speech and consequently interpretable, by listeners of good will, as a rather obscure utterance in some language with which they happen to be familiar. In the cases where persons in a state of trance have shown an unequivocal knowledge of some language of which they were consciously ignorant, investigation has generally revealed the fact that they had spoken the language during childhood and subsequently forgotten it, or that they had heard it spoken and, without understanding the meaning of the words had unconsciously familiarized themselves with their sound.
For the rest there is, in the words of F. W. H. Myers, “little evidence of the acquisition—telepathy apart—of any actual mass of fresh knowledge, such as a new language, or a stage of mathematical knowledge unreached before.” In the light of what we know, through systematic psychical research, of trance mediumship and automatic writing, it seems questionable whether any alleged demoniac ever passed the test of language in a completely unambiguous and decided manner. What is certain is that the recorded cases of complete failure are very numerous, while the recorded successes are mostly partial and rather unconvincing. Some of the ecclesiastical investigators of possession applied the language test in very ingenious and effective ways. In 1598, for example, Marthe Brossier made a great name for herself by exhibiting the symptoms of possession. One of these symptoms—a thoroughly traditional and orthodox symptom—consisted in going into convulsions every time a prayer or an exorcism was read over her. (Devils hate God and the Church; consequently they tend to fly into a rage every time they hear the hallowed words of the Bible or the prayer book.)
To test Marthe’s paranormal knowledge of Latin, the Bishop of Orléans opened his Petronius and solemnly intoned the somewhat unedifying story of the Matron of Ephesus. The effect was magical. Before the first sonorous sentence had been completed, Marthe was rolling on the floor, cursing the Bishop for what he was making her suffer by his reading of the Sacred Word. It is worth remarking that, far from putting an end to Marthe’s career as a demoniac, this incident actually helped her to go forward to fresh triumphs. Fleeing from the Bishop, she put herself under the protection of the Capuchins, who proclaimed that she had been unjustly persecuted and made use of her to draw enormous crowds to their exorcisms.
The Petronius test was never, so far as I know, applied to the Ursulines of Loudun. The nearest approach to such a test was made by a visiting nobleman who handed the exorcist a box in which, so he whispered, there were some exceedingly holy relics. The box was applied to the head of one of the nuns, who immediately exhibited all the symptoms of intense pain and threw a fit. Much delighted, the good friar returned the box to its owner, who thereupon opened it and revealed that, except for a few cinders, it was completely empty. “Ah, my lord,” cried the exorcist, “what sort of a trick have you played upon us.” “Reverend Father,” answered the nobleman, “what sort of a trick have you been playing upon us?”
At Loudun, simple language tests were frequently tried, but always without success. Here is the account of an incident which de Nion, who was a firm believer in the reality of the nuns’ possession, regarded as convincingly miraculous. Speaking in Greek, the Bishop of Nîmes orders Sister Claire to bring him her beads and say an Ave Maria. Sister Claire responds by bringing first a pin and then some aniseed. Being urged to obey, she says, “I see you want something else,” and finally brings the beads and offers to say an Ave.
In most cases the miracle was even less astounding. All the nuns who knew no Latin were possessed by devils who also knew no Latin. To account for this strange fact, one of the Franciscan exorcists explained in a sermon that there are uneducated devils as well as educated ones. The only educated devils at Loudun were those who had invaded the Prioress. But even Jeanne’s devils were not conspicuously learned. Here is part of the procès-verbal of the exorcism performed before M. de Cerisay on November 24, 1632. “M. Barré holds up the Host and asks the devil, ‘Quem adoras?’ Answer: ‘Jesus Christus.’[7] Whereupon M. Daniel Drouyn, Assessor of the Provost’s Office, said in a rather loud voice, ‘This devil is not congruous.’ The exorcist then changed his question to, ‘Quis est iste quem adoras?’ She answered, ‘Jesu Christe.’[8] Upon which several persons remarked, ‘What bad Latin!’ But the exorcist retorted that she had said, ‘Adoro te, Jesu Christe.’[9] Afterward a little nun came in, roaring with laughter and repeating, ‘Grandier, Grandier!’ Then the lay sister, Caire, entered the room neighing like a horse.”
Poor Jeanne! She had never learnt enough Latin to understand all this nonsense about nominatives and accusatives and vocatives. Jesus Christus, Jesu Christe—she had given them everything she could remember; and still they said it was bad Latin!
M. de Cerisay, meanwhile, had declared that he would willingly believe in the possibility of possession, “if the said Superior would answer categorically two or three of his interrogations.” But when the questions were asked, there was no reply. Completely floored, Sœur Jeanne had to take refuge in a convulsion and a little howling.
On the day following this very unconvincing demonstration, Barré went to de Cerisay and protested that his actions were pure, and without passion or evil intentions. “Placing the ciborium on his head, he prayed that it might confound him, if he had made use of any malpractices, suggestions or persuasions in regard to the nuns in all this affair. When he had finished the Prior of the Carmelites stepped forward and made similar protestations and imprecations; he also held the holy ciborium on his head and prayed that the maledictions of Dathan and Abiram might fall upon him, if he had sinned or been at fault in this affair.” Barré and the Prior were probably fanatical enough to be sincerely blind to the nature of their actions, and it was, no doubt, with a clear conscience that they swore these enormous oaths. Canon Mignon, we note, thought it wiser to put nothing on his head and to call down no thunderbolts.
Among the distinguished British tourists, who visited Loudun during the years of the possession, was young John Maitland, afterward Duke of Lauderdale. Maitland’s father had told him of a Scottish peasant woman, through whose mouth a
